Molecular formula : (NH4PO3)n€↕, n>1000 CAS No.: 68333♥₹ $-79-9 EINECS No.: 269-789-9 H↑✘γ£S CODE: 2835.3990 Model N∞ ≈ o.: TF-211

Product introduction

TF-211 is a phosphorus cγ®ontaining non-halogen flame re‍≤♣tardant dedicated for textile co★≈&ating.

Features

1. Halogen-free a↓ ♣→nd none heavy metal ions.

2. Stain resistance for hot w ater. Low water solub γility, not easy to precipitate&nb™ ✔sp;under high temperature and hi>"<&gh humidity conditions.

3. Good compatibility with organic p$←>olymers and resins, especially acry€β∏lic emulsion.

Product Usage

Suitable for all types of f <‌₹lame-retardant textile&¶φnbsp;coatings, especially for&>‍nbsp;hot-water-stain-resistance acry•✘∏₹lic emulsion coatinα✘↓gs.

1.Prepare textile ba♦α'cking coating: Prepare the co&∑ ‌ating according to the formula ≥≤and scratch it on the surfaceγ×¥λ of black base textile (≤↕polyester fiber). The ♥"thickness of the coating ≤0.1m"¥<÷m, and heat-treat it in the ove₽πn at 120 ℃ for 3-5min, then the t ™&est sample was obtained.

2.Hot water stain test: 60-70 ℃ hot water drip on to±¥₩ the coated side of back coatin♣πg textile, select 4 to 5 <♣•stains and drying them in the oven at < 60-70 ℃ for 10min, the test results are as fol¥♠lows:
